ISO 8601 Data elements and interchange formats – Information interchange – Representation of dates and times is an international standard covering the exchange of date- and time-related data. It was issued by the International Organization for Standardization and was first published in 198

Should you invest time in using Vim for software development? What should you do with Vim? How do you search for files? What about syntax coloring? Loading files from history, autocomplete and more.  As it turns out you don't need plugins for all this.

Why Google Stores Billions of lines of code in a single repository - this is a brief summary of a research paper published by google.

In a paper named Fixed it for you.  Protocol repair using lineage graphs it is described how machine can autocorrect programming error.

The Bellman–Ford algorithm is an algorithm that computes shortest paths from a single source vertex to all of the other vertices in a weighted digraph.

Dijkstra's algorithm is an algorithm for finding the shortest paths between nodes in a graph, which may represent, for example, road networks. It was conceived by computer scientist Edsger W. Dijkstra in 1956 and published three years later. The algorithm exists in many variants

As developers, we sometimes want to check the performance of our server, we are not system administrators so we do not run these commands on a daily basis but here is a quick overview of it.

In computer science, selection sort is an in-place comparison sorting algorithm. It has an O(n²) time complexity, which makes it inefficient on large lists, and generally performs worse than the similar insertion sort

cgroups is a Linux kernel feature that limits, accounts for, and isolates the resource usage of a collection of processes. Engineers at Google started the work on this feature in 2006 under the name "process containers".

Backtracking is a general algorithm for finding all solutions to some computational problems, notably constraint satisfaction problems, that incrementally builds candidates to the solutions, and abandons a candidate as soon as it determines that the candidate cannot possibly be completed to a valid solution

In the SQL database query language, window functions allow access to data in the records right before and after the current record. A window function defines a frame or window of rows with a given length around the current row, and performs a calculation across the set of data in the window

React is a JavaScript library for building user interfaces. It is maintained by Facebook and a community of individual developers and companies. React can be used as a base in the development of single-page or mobile applications

The fundamental structures of a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations. [1] The architecture of a software system is a metaphor, analogous to the architecture of a building. [2] It functions as a blueprint for the system and the developing project, la...

Spark is a library for structured data processing. Unlike the basic Spark RDD API, the interfaces provided by Spark SQL provide Spark with more information about the structure of both the data and the computation being performed. Internally, Spark SQL uses this extra information to perform extra optimizations. There are several ways to interact with Spark SQL including SQL and the Dataset API. Whe...

Statistics is a form of mathematical analysis that uses quantified models, representations and synopses for a given set of experimental data or real-life studies. Statistics studies methodologies to gather, review, analyze and draw conclusions from data

A recent book was published this year by Google about site reliability and security engineering, I would like to provide you a brief overview of it and incorporate my own analysis and thoughts about this subject while saving you some time from reading, at least part of it.

On-call , sometimes referred to as on-call shifts are processes used in business where employee work schedules are intentionally unpredictable. Employees who work on-call are expected to be available at any time during their shift, usually with short notice, to carry out their working duties. Depending on the nature of the profession, on-call duties may vary from what is expected during normal wor...

While there are a few types of sorting algorithms we have a few shared metrics to evaluate them all.  So when you refer me to a specific algorithm we could ask, is this sorting algorithm stable? Is it sorting in place? What is the average worst and best case running time of this sorting algorithm? Which type of data is this sorting algorithm best suited for, how much memory does this sorting...

“The Little Manual of API Design” is a very nice paper written by Jasmin Blanchette has released a paper while working in trolltech, which is a Nokia company. I found it to be very clear and concise, and reassuring what we think of API design. It’s a difficult task that includes both artistic, social, programming and scientific skills. We are going to summarize this paper for you.

In graph theory, a recursive tree is a non-planar labeled rooted tree. A size-n recursive tree is labeled by distinct integers 1, 2, ..., n, where the labels are strictly increasing starting at the root labeled 1. Recursive trees are non-planar, which means that the children of a particular node are not ordered

Brain-machine interfaces (BMIs) hold promise for the restoration of sensory and motor function and the treatment of neurological disorders, but clinical BMIs have not yet been widely adopted, in part because modest channel counts have limited their potential. In this white paper, we describe Neuralink’s first steps toward a scalable high-bandwidth BMI system

Character encoding is used to represent a repertoire of characters by some kind of encoding system. Depending on the abstraction level and context, corresponding code points and the resulting code space may be regarded as bit patterns, octets, natural numbers, electrical pulses

Raft is a consensus algorithm designed as an alternative to Paxos. It was meant to be more understandable than Paxos by means of separation of logic, but it is also formally proven safe and offers some additional features

How could you have a major boost on your programming abilities by having a better understanding of the product.  And if you do how much more effort and time would it require from you? what do you need to actually do?

A regular expression, regex or regexp is a sequence of characters that define a search pattern. Usually such patterns are used by string searching algorithms for "find" or "find and replace" operations on strings, or for input validation. It is a technique developed in theoretical computer science and formal language theory
